Hey all,

Can anyone give me suggestions on how to keep my lights cool? I just installed 4x55 watt AHSupply light kits into my canopy. After about an hour, the reflectors are too hot to touch and the whole canopy is warm.

I was thinking about installing computer fans on both ends of the canopy, but the hinges for the tops of the canopy would block off the fans. Can anyone suggest some other methods for cooling, or do I even need to keep the lights cool? You can see pictures of the lights in my gallery.

Thanks,

Mike

Just check how much they heat up the water. It's normal for reflectors to be hot and canopies to be warm.

Thanks Mario. I do have a couple other question though. I think it may sound stupid, but is it possible for the wood to catch fire from an extremely hot reflector? Also, if the wires are touch the reflector, how likely is it that the heat will melt the insulation and cause an electrical fire?

Thanks again.

The ignition temperature of wood is between 700F to 1000F (400-530C). Or, in other words, more than twice as hot as your oven on the hottest setting. No chance that your reflector will be hot enought to set wood on fire.

As far as plastic on cables is concerned: I don't know. It probably depends a lot on the cable. But my guess would be, that it's perfectly safe.

Normal T-8 bulbs are the coolest things! :lol:

IMO the best placement for a fan would be on top of the canopy, sucking the hottest air out of it and pulling in cool air from the sides. For aesthetic reasons, this is often difficult to do.

Just noticed that the back of your canopy is open... you might be alright without any forced cooling then.

Mario: Thanks, I guess I'm just being overly cautious about things. As for the wires, I think I'm going to just attach some plastic holders to the side and tie them up.

Wasser: Yea, I was thinking about installing some fans on the top of the canopy, but I couldn't figure out how to do that without making it look ugly. I think I might just get a few of those clip-on fans and have them blowing into the back of the tank. The blinds behind the tank are thick wood slats, so I think they should be able to hold up the fans.

Thanks guys.

I have all wiring in my canopy covered in plastic wire loom like this:


It not only tidies up the wiring, but also helps protect it.
